How to Generate the Lonsdor LT21-07 Lexus Smart Key PCB:

The LT21-07 must be configured for the required Lexus 8A-B6 smart key application before vehicle programming.

Identify the original Lexus smart key: Confirm the 8A-B6 system, Board No. 6100, required frequency and button layout.
Select a compatible Lonsdor device: Use the KW100, K518 Pro or supported K518 Series device with updated smart key generation software.
Open the smart key generation function: Select the compatible Lexus 8A-B6 / LT21-07 generation option available on the device.
Set the required frequency: Choose 312.09 / 314.35 MHz or 433.58 / 434.42 MHz according to the original key specification.
Set the button configuration: Select the required button values for the compatible Lexus smart key design.
Generate and verify the PCB: Complete the generation process and confirm the frequency and key configuration before vehicle programming.

Generating the LT21-07 prepares the PCB for the required smart key configuration. Vehicle programming is a separate procedure and requires supported Lexus immobilizer functions.

Lonsdor LT21-07 Lexus 8A-B6 Add Key Requirements:
